To all whom t may concern:

Be itlrnown vthat LCHARLES A." LUCK, a citizen of-the United States, anda resident of Toledo, in the county of Lucas and State of Ohio, haveinvented a certain new and useful Fountain-Pen; and I do hereby declarethe following to. be a full, clear, and exact description of theinvention, such as will enable others skilled -in the art to which itappertains to make and use the saine, reference being had totheaccompanying drawings, and to the'characters of reference markedthereon, which form a part of this specification.

This invention relates to ya fountain pen;

and has for its primaryobject the provision p of a novel construction ofthe barrel andthe cap member thereof, adapting them to be made from thinmetal, or other suitable material,in place of the hard rubber nowcommonly employed in fountain pen construction. The invention, however,does not eX- clude the use of hard rubber, .but is more particularlydirected to a construction which renders the use ofmetal practicableas asubstitute for hard rubber.

Further objects andv advantages of the in-i Figure 1 isa centrallongitudinal section l of afOuntain pen embodying one form oftheinvention withl parts in full and parts broken away. ig.'2 is afragmentary de. tail of the compression-bar locking feature in relationvto the inner and outer shells of the barrel. Fig. 3 is afragmentarycentral longitudinal section, similar to Fig. 1, with thecompression-bar in depressed position.

Fig. 1` is a central longitudinal section, simi-V e larto- Fig. 1, of aslightly modified form of the invention. Fig. 5 isa section on the line5-5 in Fig. l,.and Fig. 6 isa central longitudinal section of anotheriform ofthe iny.

Referring particularly to Figs. 1, 2 .and 3V i ofthe drawings, 1 and 2designatethe longitudinally alined rear and front endpsections,y

respectively, of theeXternal shell or casing ofa vfountain I pen barrel,embodying the invention, and 3 the internal reinforcing shell orcasingthereof,"which shells are tubular in form may be of thin metal or otherV.suitable material. The-shell 3 Yis preferably longitudinallycorrugated to render it stiffer f A.

stance, may be of stamped metal and isini serted into the section fromthe inner end j thereof and preventedv from completey passagetherethrough by coaction with the tapered outer end portion of thesection and bythe inwardly turned end edge 5 thereof.

The innen sneu s in intended to nt Closely withinthe `o uter shellsections 1 and 2 andis xeldly secured in the rear Section 1 by solderingat different points, as at 6, and with its rear end vin abutment withlthe alined .edge portion of the end closing plug 4 to n .firmly holdsaid plug to its seat in the outer end of the section 1. If desired, the

plug 4 may be soldered or otherwise xedly united to the section V1, butthis is not necessary with the end of the inner shell 3 abuttingtliereagainst. 2 has a turning lit on the inner shell 3 and is threadedto the forward end of the inner rlhe outer shell section i Yshell 3 at 7`The thread is preferably lrolled j in the section 2 so yas to formthesection with both the inner and outer threads, the former for engagingwiththe threads of the inner shell 3 and the latter for engagingv withthe retaining threads ofthe customary pen] point inclosing cap.

The inner ends of thervshellsectionsxl d.

2, whenv in assembled relationon the reinforcing shell 3, are spaced tocooperate with j the reinforcing shell to form a groove v"or run-way.for the {compression-bar lockingring Vor member 8, which is adaptedtohave turning movements therein. The locking member 8 which, in thepresent instance, is

ofsplit eccentric form, as in fountain pens 4 of the.Conklin type, maybestamped from sheet metal or formed in any other suitable manner. VTheusual compression-bar 9`for the ink-bag 10, inclosed within thebarrel,isl v provided intermediate its ends with the out-Q wardly projectingloopedlocking-ring coact- Il ing member-or`v portion 11 which is adaptedto project transversely from the barrel 'for through registering slots12 and 1,13 in the f respective inner-y and outer eshellsjthereof. ,1.The slot 13 in the outer shell section, is

be merely notches or recesses provided longitudinally in alined relationin the adj acent" ends of said sections. 1t is evident that when thesplit portion of the locking-ring 8 isin vregister with the coactinglocking-ring- 11 of the compression-bar, such member may be forcedinward to impart a bag compressing movement to the 'bar 9, and that whensaid bar is in normal position and the locking ring turned through theopening in the locking member 11, said member and bar will be firmlyheld by the camming action of the ring in their retracted or normalpositions. 685,258 and 745,481, issued October 29, 1901, and December 1,1903, respectively'V to Roy Conklin covering the Conklin form ofcompression-bar locking means discloses several forms of such lockingmeans and it is, therefore, not thought necessary to includeillustrations of such different locking means in the present case. Itwill be understood, therefore, that the form shown herein is merelyillustrative of the idea and is not intended to limit the inventionherein covered to the use thereof.

The outwardly projecting or control member 11 for the compression-bar 9is intended, when in its normal or outwardly projected position, toperform the additional function of locking. the inner shell 3 togetherwith the rear outer section when attached thereto, and the removableouter shell section 2 in assembled position by reason of the member 11passing through the slot 12 of the inner shell and through the slot ornotch 13 in the outer shell section 2, thereby locking the members 2 and3 against relative turning movements and preventing a consequentunscrewing of the section 2 from the shell 3. Such unscrewing orremovalof the section 2 from the shell 3 may be accomplished, however, when thecompressing bar 9 and its control member 11 are sufiiciently depressedwithin the barrel to withdraw the member 11 from within the slet ornotch 13 of the barrel section 2. lt is, therefore, evident, so far asthe barrel section locking feature of the member 11 is concerned, thatit may be of any other form, suitable for the purpose, than thatillustrated, as any outwardly projecting part or control member for thebar 9 might accomplish the same purpose.l

ln this form of the invention the section 2 of the outer barrel shell isformed at the outer end of its thread 7 with an extension 14,4 whichgradually reduces in diameter toward its outer end toresemble inappearance the customary pen point carrying end or section of a fountainpen. rlhe pen point carrying section proper, which is designated UnitedStatesLetters Patents Nos. Y

15 and is'preferably of hard rubber to avoid corrosion, by reason of itscontact with the ink, is fitted into the extension 14, being insertedinto the shell section 2 from the inner end thereof, and is held firmlyto its seat in the extension 14, by reason of the abutment of thethreaded end of the inner shell 3 against its-inner end when the barrelsection 2 is screwed home in proper position on the inner or reinforcingvsection 3. The pen carrying section 15 is provided longitudinallytherethrough with an ink feed passage 16 in communication at its innerend with the ink bag 10, which is carried by saidy section, and thecustomary feed-bar 17 and penpoint 18 are secured in this feed passage,as

well understood in the art. Ink the present instance, the pen-point andfeed-bar are shown as secured within the passage 16 by an eccentriclocking nipple 19v forming the subjectV matter of my Patent No.1,315,373, dated September 9, 1919.

In the form of the invention illustrated in Figs. 4 and 5, thevoutershell of the barrel has its sections, which are designated 1a and 2, inabutment at their inner ends and the retaining groove for thelocking-ring 8 is formed by the provision of longitudinally spacedannular ridges or beads 20 formed in the outer shell, one at each sideof the line of division or abutment of its sections. The outer shell inthis form is shown as terminating with the threads 7 so that the pencarrying section 15 may thread into the threaded portion 7 of the innershell 3 and have the shoulder 22 at the base o-f its 'thread abuttingagainst the adjacent ends of Vthe inner and outer shells.

The form of the invention illustrated in Fig. 6 differs from thatillustrated in Fig. 4 in that the outer shell, which is designated 23,is formed in a single instead of in two sections, the inner shell 3being freey for longitudinal movement and toturn within the entire outershell.

1t is evident that I have provided a simpleand cheap construction of penbarrel, which may be of metal or other suitable material; that thesections of the barrel may be quickly assembled; that the sections ofthe barrel are locked in assembled relation by the control member of theink-bag compressing bar, and may be released by a movement of suchcontrol member from its normal position. Y f

ylt is also evident that if it is desired to make a gold finishedbarrel, the outer shell thereof may be composed of thin rolled gold orplated as desired, the inner' shell being of sufiicient strengthvandrigidity to reinforce the outer shell against compressing, twisting orbending stresses.

l wish it understood that my invention is not limited tol any specificconstruction, arrangement or form of the parts, as it is l.
